Subproblem 1

Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0

Subproblem 2

Set the factor '(-1cos + 3)' equal to zero and attempt to solve: Simplifying -1cos + 3 = 0 Reorder the terms: 3 + -1cos = 0 Solving 3 + -1cos = 0 Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + -1cos = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -1cos = 0 + -3 -1cos = 0 + -3 Combine like terms: 0 + -3 = -3 -1cos = -3 Add 'cos' to each side of the equation. -1cos + cos = -3 + cos Combine like terms: -1cos + cos = 0 0 = -3 + cos Simplifying 0 = -3 + cos The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.
